Thundercats is one of the highest rated cartoons that came from the eighties. The cartoon was based on a large group of human shaped members of the cat family. On the island that they had to leave, Thundera, they were royalty and in leaving the planet they left all that they knew. They landed on a planet called Third Earth were they set up their new lives.
The Thundercats were not alone on the island. There was an evil mummy called Mumm-ra who with the help of his evil henchmen wanted to rule Third Earth and wanted to destroy the Thundercats. Lion-o, the leader of the Thundercats, took charge and with the help of his magic sword of Omens defended the plant and saved the other inhabitants from the evil rule of Mumm-ra.

Thundercats was an American animated television series developed by Rankin/Bass. It aired 1985-1990 & then had a run on cable television's Cartoon Network 1997-2002. Thundercats were a race of cat-like humans, each named according to what type of cat it represented: Liono was lion-like, Cheetarah was cheetah-like, Pumara was puma-like, etc... They were from a planet called "Thundera" which was destroyed. Only a handfull of their race survived & travelled to a new planet they called "New Thundera", but it was also sparsely populated by half animal, half man creatures such as beastman, monkeyman, hyenaman, etc... The thundercats arch nemesis however, was an evil humanoid mummy called "Mum-ra". Their catch-phrase was "Thundercats, HO!"

As in: "Remember that Thundercats cartoon from the 80's? I thought it was pretty cool back then."

Massively popular cartoon of the eighties. The only better cartoon was masters of the universe. Following a similar style to MOTU, Thundercats delivered some interesting storylines, and also tought the viewers a sense of morality. Something the power rangers generation didn't get.

An act done upon some poor unsuspecting male. A person approaches from behind, and uppercuts between their legs with their thumb, pointer, and middle fingers all straight up in a triangle pattern, making sure the thumb contacts the butthole, and the pointer and middle finger pokes both testicles. All while shouting "THUNDERCAAAAAAAAAAT!" as loudly as possible.
